CHAIR FOR RAILROADS. l

Specification of Letters liatent N 0,

scription thereof, reference being had to the accompanying drawings,making part of thls specification, in wh1ch Figure 1, 1s a crossvertical section taken in the plane of the junction of the rails;

Fig. 2 a side elevation of the rails in the chair; Fig. 3, a sectiontaken in the central longitudinal plane of the rails; Figb a plan of therails, chair and sleeper.

The same letters indicate like parts in all the figures.

The object of my said invention is to secure the junctions of thesections of rails so as to insure the retaining of them in line, and tothis end my said invention consists in the employment of a chair withlips to extend over the web or base of the rail, and

with a grooi e or other suitable receptacle for a cross wedge which isto be used in combination therewith, and which is to be driven acrossthe longitudinal plane of the rail and just under the base of theproximate ends of two sections so as to force the webs of the said railsup against the two lips of the chair, and at the same time to form abase for them to rest on, whereby I am enabled to keep the proximateends of the sections of rails in line and on the same level, and avoidthat hammering actlon whlch 1s so 1n ur1ous to rails, and all the otherdifiiculties consequent upon the use of imperfect modes of securing theends of rails in chairs.

In the accompanying drawings (A) represents the chair, which may besecured. in any suitable manner to the sleeper or cross tie (D)- Thischair is formed with lips (b, b) to extend over the web (0, c) or baseof the rails (B) while the under surface of the web or base rest-s onthe flat surface of the chair between the lips. I prefer so to form theunder surface of the lips (b, b).

that they shall fit the upper surface of the web (a, c) of the rails.The upper surface of the base of the chair, on which the base of therail rests is formed with a groove (0?) at right angles with thelongitudinal plane the two lips (I), b) ofthe chair and slotting 26,492,dated Dec mbrao; 11859.1 :1, w
